In the nineties the invention of the InGaN blue LED has innovated illumination technology. Currently LCD backlighting and more and more general lighting applications are based on white LEDs comprising of inorganic phosphors and blue emitting InGaN chip. Well established phosphor materials are ortho silicates and garnets like yellow emitting YAG:Ce. In our paper we demonstrate that garnet materials also allow for green light emission for both, general lighting and backlighting LED applications.

As the inner diameter of CCFL is increased in the range of outer diameters 3~5 mm, the luminance efficiency is increased by the low power consumption. For the outer diameter 5 mm, the efficiency is linearly increased even at the range of a high current.

본 실험은 구두매장 벽면 진열장을 연구대상으로 하여 바람직한 벽면조명환경을 제시하고자 실험을 실시하였다. 그 결과, "차별성"이 요구되는 벽면 조명은 광원 종류를 다양하게 하고 전반조명과 중점조명의 조도 비를 크게 하거나, 전반조명과 중점조명의 조도 비는 작으나 전체조도를 높게 하는 것이 효과적이었다. 또한 "명시성"이나 "정서성"이 요구되는 벽면 조명은 광원의 종류를 다양하게 하고 전반조명과 중점조명의 조도 비가 작으면서 전체조도를 높이는 것이 좋은 것으로 나타났다.

Museums have developed various needs of the visitors and exhibits over the past two centuries. Currently, they have multiple functions of display, conservation, research and public education about artworks and cultural events. Therefore, exhibits should be displayed in various ways so that visitors can feel inter-relations with exhibits. The exhibition areas of museums should be provided with the stable lighting environment for visitors and artworks. For the study, I selected four museums, which were the Seoul Museum, the Mimesis Art Museum, the Seoul Museum of Art in Nowon and the National Museum of Modern and Contemporary Art in Gwacheon, and I measured illumination levels of the selected Museums, and then, I surveyed the visitors' responses on the lighting conditions of them. According to the results, the measurements of the illumination levels in the four museums showed that the illumination levels of them were effectively controlled to display the art works. However, the illuminance levels at some areas that drew the natural light as lighting source were much higher than recommended illumination values for museum. In the mean time, the answers of questionnaires showed that the natural light were so effective to light the museums although the natural light provided some areas with high illumination levels.

The outdoor lighting is provided for a variety of purposes, for work or recreation, for safety or security, for amenity and for advertising or display. But the effects of lighting on the natural environment can be difficult to quantify. At present, in many countries, various policies to manage the light trespass from outdoor light have been planned. For example, Model Lighting Ordinance(MLO) will allow communities to drastically reduce light pollution and glare and lower excessive light levels. The recommended practices of the IES can be met using readily available, reasonably priced lighting equipment. So, it this paper, we analyze the effect of road lighting on light trespass using by RELUX program. And then we consider the possibility of practical application of BUG rating in Korea.

Low road lighting is a lighting device that complements the shortcomings of existing pillar-type street lights. It is a lighting device that emits light from the side of the road surface and adjusts the luminance of the road surface like a light carpet. In this paper, to achieve full commercialization, we analyzed the luminance of the installed road surface and studied whether lighting could replace existing road lighting. In this study, the LMK (Luminance Measurement Camera) LABSOFT program was used to measure and analyze the surface luminance of road lighting, and the RELUX program was used to evaluate and analyze the simulation performance to determine light-based lighting conditions. A study was conducted to determine whether replacing pillar-type road lighting with low-level road lighting in a real environment would ensure comfortable and safe night vision for drivers at night.

Recently the government banners green growth promises as a paradigm of national development which are to reduce greenhouse gases and environmental pollution by exhaust gases from automobiles. Existing in all countries around the world by using fossil fuels to minimize environmental changes are developing a new alternative energy sources. Among the emerging alternative energy, using solar energy technology is applied across the industry, but the maintenance and repair to integrate solar cells and has been a problem occurs. To prolong the life of cells integrated on a solar cell is exposed when the non-eye, etc., when not integrated by the solar cells should not be exposed. In order to resolve these contradictions, a intellectual solar green street lighting was developed by using Q(Quick)-TRIZ.

Purpose - The objective of the paper is to examine display techniques and tools at traditional clothing stores to improve the traditional market. Since most research has been done theoretical and model based approaches, changing business environments requires more holistic and detailed facts to apply or develop a retail business strategy. Research design / data / methodology - The study employs qualitative research such as direct observation as well as direct interview and telephone interview from May 7 to Jun 2, 2012. The paper examines lighting, various display techniques and tools. The analysis of 80 store pictures for them had been done three examiners with agreement. Results - Sample garments are displayed on the walls; the racks of hangers are attached on the upper part of the walls; there is indirect lighting only. Furthermore, the merchandises are displayed, without any consistency, on various sizes and shapes of hangers, only on the owners' arbitrariness. When considering that the Korean traditional fabrics (Juddan) have a little pattern and colors as their important elements for displaying. Conclusions - The findings of this study show that the retailers in the traditional market need to have lessons on colors and to learn how to use the specific lighting and to display merchandise.
